Tissue slices of zucchini squash (Cucurbita pepo L., cv. Tigress) fruit were exposed to ultraviolet-C (UV-C) radiation from germicidal lamps for 1, 10 or 20 min; however, only 10 and 20 min UV-C exposure significantly reduced microbial activity and deterioration during subsequent storage at 5 or 10 degrees C. UV-C treated slices had higher respiration rates than controls; however, the ethylene ...

abstract effect of different concentrations of salicylic acid on postharvest life of kiwifruit (actinidia deliciosa) cultivar hayward at 0 ±.5 °c and 90-95% rh was studied. fruits were treated with salicylic acid (0, 1 and 2 mmol/l-1) and stored at 0±.5°c for 16 weeks. fruit quality attributes assessment including firmness, total acidity, soluble solid content, ascorbic acid, antioxidant activi...

Treatment of peppers with hot water (53°C) for 4 min was found to be effective in alleviating chilling injury and reducing decay after 14 and 28 days of storage at 8°C. Treatment at 45°C for 15 min was less effective in maintaining pepper quality during storage. Packaging with low density polyethylene film significantly reduced weight loss and chilling injury during low temperature storage. Low...

in this study, the effect of salicylic acid (sa) on root knot nematode (meloidogyne javanica) pathogenicity and induction of some defense mechanisms such as polyphenol oxidase enzyme activity and total phenol accumulation were investigated in greenhouse conditions. we demonstrated that application of 5mm salicylic acid through foliar spray could induce resistance against m. javanica in tomato. ...

Electrets are polymeric discs that carry semi permanent electrostatic charge. These provide electrostatic potentials in the range of 500 to 3,000 V. In the current work, the effect of electret exposure on the skin permeability was investigated. Transdermal transport studies were carried out across porcine epidermis in Franz diffusion cells. Salicylic acid, fluorescein labeled dextrans (FD) and ...

Plants often respond to attack by insect herbivores and necrotrophic pathogens with induction of jasmonate-dependent resistance traits, but respond to attack by biotrophic pathogens with induction of salicylate-dependent resistance traits. To assess the degree to which the jasmonate- and salicylate-dependent pathways interact, we compared pathogenesis-related protein activity and bacterial perf...

introduction soybean (glycine max (l.) merrill) is a leguminous annual crop belonging to the fabaceae family, that because an important source of food containing 20 to 28 grain oil percent and high protein is the most important oilseed of worldwide interest. recently, cultivation of this plant is considered as a valuable oil plant in crop rotation. drought, salinity, heat and freezing are envir...

Low temperature is one of the major factors limiting pepper (Capsicum annuum L.) production during winter and early spring in non-tropical regions. Application of exogenous abscisic acid (ABA) effectively alleviates the symptoms of chilling injury, such as wilting and formation of necrotic lesions on pepper leaves; however, the underlying molecular mechanism is not understood. The aim of this s...
